Abstract
A reaction vessel has a reaction chamber, and two or more plasma nozzles coupled to the reactor chamber. Each plasma nozzle has a microwave plasma generator powered by a magnetron, and a feed tube for directing a flow of material via the plasma generator to a respective inlet to the reaction chamber whereby the plasma generator at least partly ionises the material to form a plasma prior to entry of the at least partly ionised material into the reaction chamber. The plasma-generating region of each nozzle is separated from the reactor chamber at a distance between 0.005 to 1 m.

36. A reaction vessel comprising:
-
a reaction chamber; and two or more plasma nozzles coupled to the reactor chamber, wherein each plasma nozzle comprises; a microwave plasma generator powered by a magnetron, and a feed tube for directing a flow of material via the plasma generator to a respective inlet to the reaction chamber whereby the plasma generator at least partly ionises the material to form a plasma prior to entry of the at least partly ionised material into the reaction chamber, and wherein the plasma-generating region of each nozzle is separated from the reactor chamber at a distance between 0.005 to 1 m. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 54, 55)

50. A plasma nozzle for feeding plasma to a reactor chamber comprising:
-
a plasma generator; a feed tube for directing a flow of material from an inlet via the plasma generator; and a nozzle outlet remote from the plasma generator, wherein the nozzle outlet is adapted to couple to a reaction chamber whereby the plasma generator at least partly ionises the material to form a plasma which is sustained to flow through the nozzle outlet by employing a magnetron as microwave source comprising at least one waveguide dimensioned for microwave radiation intersecting the feed tube at or near a position at which the electric field of the microwave radiation is most intense, wherein the plasma-generating region of each nozzle is separated from the reactor chamber at a distance between 0.005 to 1 m, and wherein the nozzle includes two plasma generators, each with a respective plasma-generating region, arranged such that the feed tube intersects both plasma-generating regions. - View Dependent Claims (51)

52. A hydrogen generating vessel comprising:
-
a means for connecting to a supply of a gaseous hydrocarbon; at least two plasma nozzles coupled to the means for connecting; and a reaction chamber coupled to the at least two plasma nozzles, wherein each plasma nozzle comprises; a microwave plasma generator powered by a magnetron, and a feed tube for directing a flow of the hydrocarbon via the plasma generator to a respective inlet to the reaction chamber whereby the plasma generator at least partly ionises the gaseous hydrocarbon to form a plasma prior to entry of the at least partly ionised hydrocarbon into the reaction chamber, wherein the reaction chamber includes at least one outlet via which hydrogen is collected, and wherein the plasma-generating region of each nozzle is separated from the reactor chamber space at a distance between 0.005 to 1 m.

53. A carbon extraction vessel comprising:
-
a means for connecting to a supply of a gaseous hydrocarbon; at least two plasma nozzles coupled to the means for connecting; and a reaction chamber coupled to the at least two plasma nozzles, wherein each plasma nozzle comprises; a microwave plasma generator powered by a magnetron, and a feed tube for directing a flow of the hydrocarbon via the plasma generator to a respective inlet to the reaction chamber whereby the plasma generator at least partly ionises the gaseous hydrocarbon to form a plasma prior to entry of the at least partly ionised hydrocarbon into the reaction chamber, wherein the reaction chamber includes at least one outlet via which the carbon is collected, wherein the plasma-generating region of each nozzle is separated from the reactor chamber space at a distance between 0.005 to 1 m, wherein the manner of collection of the carbon determines the predominant form of carbon collected, and wherein the reaction chamber includes a substrate onto which carbon is preferentially deposited, the carbon being collected by removal of the substrate from the reaction chamber.
